The effectiveness of implementing inquiry activities into the teaching process in the phase of revising and deepening the learning content

The aim of research was to verify the effectiveness of implementing the inquiry-based teaching (IBT) into the teaching process of chemistry in secondary school in the phase of revising and deepening the previous-year learning content. The results of the research confirmed a significant difference on the level of knowledge and skills between the experimental group students (N=143) where the IBT was implemented and the control group students (N=149) where traditional teaching methods were implied.
